120VAC Snow Melting Cable

ProMelt Cable, 15 Sq.Ft., 50W, 120V

ProMelt Cables cost less than ProMelt Mats and give
you more layout options.

In both products, the heating elements are surrounded
with the same high-temperature ETFE and engineered
polyurethane outer jacket for long life and jobsite
toughness, including installation in asphalt.
ProMelt Cables are usually tied to reinforcing wire 3 or
4 inches on center. That provides either 50 or 38 Watts per
square foot. ProMelt Cable can go perimeter to perimeter
or fill odd-shaped areas for complete snow melting
coverage.
There are a lot of ProMelt Cable sizes in stock in four
single-phase voltage options. All the cables terminate
at one end with a power lead so you only make one
connection to your electrical source.

ProMelt Cables save on material costs, give you more
flexibility and carry a 10-year limited warranty.

Follow these recommendations when selecting
ProMelt Cables:

Determine what voltage will be used:

120V, 208V, 240V, or 277V.

Determine the heat output.

The climate and amount of snowfall
will dictate this choice. In general, most
systems will require 50 Watts/Sq.Ft.
spacing (3” o.c.) to melt snow and ice.
Some residential or light commercial
systems in temperate climates, may
need only 38 Watts/Sq.Ft. spacing
(4” o.c.).

Determine the square footage of the area to be melted.

Do not include areas under built-ins
like planters or similar obstructions.
Stay 3-6” from edges of slabs and do
not cross expansion joints if possible.
Add up all the areas to be melted
and round down to the nearest cable
size(s) to fill the area.

Alternatively, you might want to figure
the total length of cable needed. This can
be better for an area such as tire track
melting. As an example, a 24”-wide track
with 3” o.c. ProMelt Cable will go back and
forth eight times to fill a 24”-wide track. If
the tire track is 25’ long, then each track
will need 8 lengths x 25 feet or a total of
200 feet of cable.

More than one cable can be used
to melt an area. Combine cables in a
manner not to exceed the capacity of the
electrical control selected. If using our
ProMelt ContactorPro controls, each area
should not exceed 50-amps, since these
controls are built with 50-amp contactors.
Therefore, we recommend dividing the
area(s) into “sub-zones”, if necessary or
desired, to minimize the cable amp load
connected to each contactor.
